Many experts say antigen testswhich are believed to be a better measure of infectiousness for those who are symptomatic because the tests are less sensitive than PCR testsshould be used as an additional precaution, while others have raised concerns the CDCs guidance lacks clarity. The study, High Rates of Rapid Antigen Test Positivity After Five Days of Isolation for COVID-19, has not yet been peer reviewed. Having them return to work before 10 days of isolation without a negative rapid antigen test may increase the risk that they spread the virus to others, the researchers said. Last week, the CDC recommended a shortened isolation times for health care workers who test positive but are asymptomatic. High rates of rapid antigen test positivity after 5 days of isolation for COVID-19.

The research only fuels the ongoing discussion about how long people should isolate after they contract the virus, experts say. Those who returned early had to follow strict masking and distancing guidelines. However, Dominguez said, the odds of dead virus and dead virus alone triggering a positive antigen test in a human rather than a petri dish are low. "This study is one of the first to inform the care of patients who continue to test positive for COVID-19," says Ayush Batra, MD, a Northwestern Medicine neurocritical care specialist who treats patients with COVID-19 and co-authored the study. Its important to take into account other factors such as symptoms and immunity status. Opens in a new tab or window, Visit us on Instagram. A woman takes an at-home rapid Covid test. But they stressed its essential to also follow existing public health measures, such as strict masking.

A new study from Harvard University that looked at a small number of cases from the National Basketball Association's COVID-19 testing program found that more than half of Omicron cases identified within a day of a previous negative test were still infectious 5 days after a first positive test, dipping to 25% on day six and 13% on day seven. Are they contagious at the end of their infection period? Imposing a universal negative rapid test requirement could unduly extend isolation for those who are no longer infectious, researchers concluded, though they noted proper mask-wearing and avoiding crowded venues for 10 days is key for those who could still be contagious. More sensitive PCR tests, which can take several days to process and can produce positive results long after someones infectious period ends, are better fits to diagnose COVID-19, rather than clear someone to return to work, they said.

As a precaution, those who test positive are encouraged to wear a well-fitting face mask through day 10, even though the risk has gone down at that point. Jennifer Henderson, Enterprise & Investigative Writer, MedPage Today The Biden administration is buying a billion rapid antigen tests to ship to American homes, aiming to address the need for increased Covid testing and ease a nationwide shortage of tests. The research team examined 309 rapid antigen tests performed on 260 UChicago Medicine healthcare workers between January 2 and January 12, 2022. If enough proteins snag on the fence, a visible line of color will appear. Home. Heres what we know. People who are vaccinated and boosted may be more likely to remain COVID-positive after five days of symptom onset if they get sick, according to a preprint study.
